packages in testing for a long time?

Now that the new kernel and Xorg packages have been promoted out of testing, it's a lot easier to see what else is in there. I looked and saw that there are a few things that have been there for a surprisingly long time:

- 4 "telepathy"-related packages since November- libfetch (for a pacman experiment?) since January- autofs since January- kdevelop and kdevplatform since February

Everything else is no older than a month. What's up with these oddball older things?
